I began to take an interest in Benjamin's music because of his connection to Messiaen, but found most of what I heard rather underwhelming. The piece that really works for me the ravishing and ethereal Dream of the Song, for countertenor, chorus and orchestra. I heard this in Paris, conducted by Daniel Harding, along with some Wagner and Brahms, and I think it can be found on youtube. I might try his opera Written on Skin if it is performed again.
